What CAT preparation resources are available for free or self-study?

Free resources can genuinely get you to 99+ percentile on CAT, including a score competitive enough for IIM Calcutta's cutoff of around 99.5 percentile for General category males.

The catch

free tools require twice the self-discipline that paid coaching enforces for you. This path is real, but it is narrow and unforgiving.

YouTube Channels and Video Playlists

Rodha's YouTube channel is the single most recommended free resource across Reddit and Pagalguy, offering topic-wise playlists covering Quant, LRDI, and VARC at a depth that rivals paid programs from TIME or Career Launcher. Unacademy's free CAT playlist, Handa Ka Funda for arithmetic fundamentals, and Arun Sharma's official walkthroughs round out the core video library.

One consistent Reddit finding: aspirants who watch videos without immediately solving 15-20 related problems retain almost nothing. Budget two hours of practice for every one hour of video, without exception.

Official Mocks and Question Banks

The IIM CAT official mock tests, released every October, are non-negotiable. They replicate the exact interface, sectional timing, and difficulty gradient of the real exam, and no paid mock fully replicates this. Beyond the two official mocks, these free sources extend your practice meaningfully:

• Oliveboard freemium tier: sectional tests and mini mocks
• Cracku daily practice sets: strong for LRDI sets
• Pagalguy question bank: community-curated, well-tagged by topic
• Previous CAT papers from 2017 onwards: available on coaching institute blogs and highly relevant

Time every practice set under exam conditions. Untimed practice is comfortable but teaches you nothing about your actual test performance.

Books and Reading Material

Arun Sharma's Quantitative Aptitude, LRDI, and Verbal Ability books cost under ₹500 each on Amazon and cover roughly 80% of the tested syllabus. Nishit Sinha's LRDI workbook handles the harder puzzle-type sets that CAT has trended toward since 2019.

For VARC, daily reading from The Economist, The Hindu editorial pages, and RC passages from free LSAT prep sites builds the reading speed IIM Calcutta's RC section demands. LSAT passages are underrated.

They are dense, argument-heavy, and closer to CAT's RC style than most Indian prep material.

Community Forums

Reddit's r/CATpreparation and Pagalguy's CAT forum are where free-resource strategies get stress-tested by real aspirants. Both communities share annotated notes, discuss LRDI set strategies, and post detailed score-improvement logs.

Telegram groups distribute compiled question banks and shortcut PDFs, though material quality varies significantly and some PDFs circulate without authorization. Filter aggressively: posts from aspirants who have already converted IIM Calcutta, IIM Bangalore, or IIM Ahmedabad calls are far more useful than generic advice.

A purely free-resource approach to reach IIM Calcutta's cutoff demands roughly 300-350 hours of structured preparation over six to eight months. That is achievable.

But if your mock scores stagnate for more than six weeks, that is your signal to either change strategy or consider one targeted paid course, not the whole package.
